I'm still asking, "Is time_step a measure of time duration", and if I am understanding this, it is.
If it is, one second contains 16 ticks.
from the manual:
If time_step changes suddenly, speeds become inaccurate
Now, I can't reconcile those two things.
Anyway, no need to belabor the point in this thread. Maybe it'll get thru to me after a while. I'll work on it. Thanks.
